PHP: Prevent function return from function?

Question

How can I make sure that the function startProcess();is called, but does not stop execution for myFunction(). I suppose there is a way to call a function and not let it return its value in order to do this in this way?

Pseudo Code:

function myFunction() {

    startProcess();

    return $something;       
}

function startProcess() {
    sleep(5);
    // Do stuff that user doesn't should have to wait for.
}

Answer 1

You cannot do this. PHP has several functions that allow you to use asynchronous I / O, but you don't need anything like concurrency.

The reason for the lack of language support is that PHP is designed to run short-lived scripts, and concurrency is controlled by the HTTP daemon.
